I have 6 Cairnsmore boards that hash, but not up to standard.

Two of the boards kick out 50% hardware errors, resulting in an effective hashrate of ~400 MH/s
3 boards have one pair operating below standard for hash rates ~600 MH/s
1 board was programmed with 170 MH/s bitstreams, so it is running at ~680 MH/s

All of these are less than one year old, so the Enterpoint warranty should apply.  I don't have the time to chase returns so I haven't pursued that option.  It is also possible that re-programming the boards with HashVoodo, or Makomk's faster bitstreams with give you substantially better results.  I haven't had the time to try.

All boards are up for Auction sale.  When the auction closes I will ship the boards from best to worst in order of the highest bids.





Terms of Sale
Payment in BTC only
Escrow with John K.
Orders of 2 or more will ship stacked for side cooling and include up/down cables
Buyer pays shipping 0.3 BTC within USA, cost plus 0.1 BTC international
Auction Closes Sunday at 12 PM Eastern time Escrow payment due within 24 hours, shipping will be ASAP from confirmation of escrow payment

Shipping is flat for any number of boards.

The reserve price is 3 BTC.

Escrow fees should be paid by the buyer.  I recommend 0.1 BTC / board

Do some of them stop hashing and then do you have to manually restart them (unplugging power and/or USB)? How often?

Trade BTC for €/$ at bitcoin.de (referral), it's cheaper and faster (acts as escrow and lets the buyers do bank transfers).

The CM1s have very sensitive on USB.  By discarding USB cables on any boards that drop out, and using good, powered USB hubs, I have reduced the drop out incidents to ~1-2x per week on the 140 odd boards that I have.

I will ship these units with the known good USB cables they are running on now.

Thanks.
